Definitions
- the present disclosure relates to dye-sensitized solar cells and a method for making same. More particularly, the disclosure relates to a dye-sensitized solar cell that utilizes 10 H -phenoxazine- or triphenylamine-based dyes as the dye-sensitizers.
- Dye-sensitized solar cells provide a technically and economically credible alternative concept to present day p-n junction photovoltaic devices ( M.

orifice 18 that goes through thesecond substrate 20 and the second conductive layer) between thefirst substrate 10 and thesecond substrate 20, in some embodiments, a sealant (not shown) is applied to seal the DSSC. One of the functions of the sealant is to prevent the regeneratingcomposition 24 from escaping from between thebarrier layer 11 and the secondconductive layer 22. Exemplary sealants include, but are not limited to Surlyn® ethylene methacrylic acid copolymer resins available from DuPont™. -
FIG. 3 shows a dye-sensitizedsolar cell 30 according to an embodiment of the invention. Thedye 16 comprised in thenanoparticulate layer 14 and themicroparticulate layer 13 is excited with light and transmits electrons into thenanoparticulate layer 14, whendye 16 absorbs solar energy. At this point, thedye 16 is in an oxidized state. As shown, anelectric flow path 32 inFIG. 3 , electrons are transmitted to theconductive layer 12 to the secondconductive layer 22 to generate a current. Thereafter, electrons from regeneratingcomposition 24 are provided to dye 16 for reduction of oxidizeddye 16. The above oxidization and reduction ofdye 16 is repeatedly performed to generate current continually. -
FIG. 4 shows a flow chart for making a dye-sensitized solar cell according to an embodiment of the invention. A first substrate is provided, asstep 100. A first conductive layer is formed on the first substrate, asstep 102. A barrier layer is formed on the first conductive layer, asstep 104. A nanoparticulate layer, comprising a plurality of nanoparticles, is formed on the barrier layer, asstep 106. A microparticulate layer is formed on the nanoparticulate layer, asstep 107. A dye is then applied on the first substrate by dip coating, asstep 108, such that the dye is present in the nanoparticulate layer and/or in the microparticulate layer. Thereafter, a second substrate is provided, asstep 110, where the second substrate comprises a second conductive layer. As shown instep 112, a regenerating composition is applied between the substrates to yield a dye-sensitized solar cell, e.g., through an orifice present on the second substrate, that goes through the second conductive layer. In some embodiments, a sealant is provided (step not shown) in a sealing step after the regenerating composition is applied. - The following examples are set forth to assist in understanding the embodiments of the invention and should not, of course, be construed as specifically limiting the embodiments of the invention described and claimed herein.
- A DSSC is prepared by deposition of several layers, including a TiO2 nanoparticulate layer onto a fluorine-doped tin oxide glass substrate. The substrate comprising the TiO2 nanoparticulate layer is dipped in a 0.3 mM solution of dye and allowed to soak in the dye solution for 30 minutes. After soaking, the substrate comprising the TiO2 layer is washed in deionized water, dried, and then washed again in isopropanol.
- The DSSC is assembled by placing the substrate comprising the TiO2 nanoparticulate layer and dye on top of a back conductive surface having an orifice. An electrolyte containing 0.06 M LiI, 0.04 M I2, 0.5 M 1-butyl-2-methyl imidazolium iodide, 0.5 M 4-tert-butylpyridine in 5:1 acetonitrile/valeronitrile is applied through the orifice, which is subsequently sealed. The completed DSSC is sealed with a low melting point polymer film that served as a gasket.
- Embodiments of the invention described and claimed herein are not to be limited in scope by the specific embodiments herein disclosed, since these embodiments are intended as illustration of several aspects of the disclosure. Any equivalent embodiments are intended to be within the scope of this disclosure. Indeed, various modifications of the embodiments in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.
